Question 738802
 y= Log to the base 2(x+1)-3 
I have to graph it. 
I also ned to make a table. I started the table 
x y
-1/2 -4
0 -3
9 -2 
but thats all I have. I don't know how to find the next few coordintes.
-----------------
{{{y = log(2,x+1) - 3}}}
You can change the base to 10 and use a calculator.
{{{y = log((x+1))/log(2) - 3}}}
A calculator is tedious, an Excel sheet is better (and you're less likely to make a mistake).

It will make a table, and do the graph.
